14. Mask Options
Mask option are available on the EM6680, on EM6580 options are accessible through specific registers that are
only present into the EM6580. These registers are name RegMFPn (n 0,1,2 and 3) and are mapped within a
free range addresses, from address 75h to 7Bh
14.1 Port A Metal Options
Table 14.1.1 Pull-down Metal mask Options
NO pull down option is already software controllable with register as in the EM6680.
Table 14.1.2 Pull-up Metal mask Options
